specification of 1,043,072. Patented Nov. 5,1912.

Application filed November 1, 1911. Serial No. 658,043.

To all who'm, 'it may concer'n:

Be it known that I, GEORGE O. CORNELL, a citizen of the United States, residing at Canton, in the county of Bradford and State of Pennsylvania, have invented certain new longitudinal and transverse slits 8. This closure flap 6 is quite narrow in comparison to the flap 5 as will be seen from reference to Fig. l of the drawing and the latter flap at its free edge laps upon the flap 6 when and useful lmprovements in BoX-Fasteners, said flaps are folded inwardly. The edge of of which the following is a specification, refthe flap 5 is provided with a plurality of erence being had to the accompanying drawspaced looking tabs 9 which are of substantially semicircular form at their ends and are slightly offset to form the laterally extending squared Shoulders 10. The relatively narrow neck- 11 which connects the ends Vof these tabs with the body of the flap 5 is of slightly less width than the slits or incisions 7 in the flap 6, andthe enlarge ends of the tabs are adapted to be inserted through said slits by pressing upon opposite oorners of the box body at each end and inserting the shouldered ends? 10 through said slits so that the enlarged semicircular ends of the tabs vmove into and through said slits in both .a longituclinal and transverse direction when the box body assumes its natural form upon the release of pressure thereon. It will thus be seen that when the tabs are in their looking positions the Shoulders 10 thereon are disposed beyond one end of the slits 7 thus preventing any relatlve transverse movementof the flaps 5 and 6 which would tend to separate the same. As an additional means of security, I provide the end flaps 12 which are adapted to be folded inwardly upon the end portions of the side flaps 5 and 6. As previously stated the iap 6 is provided at its ends with the intersecting slits 8 and adjacent to the attached edge of. the flap 5 the same is provided with the transverse slits 13. The looking tongues 9 on the free edge of the flap 5 which are disposed nearest the ends of said flap are also provided with the transverse slits 14. Upon the edges of the end flaps 12 and adjacent to' their ends the tongues 15 are formed and these tongues are adapted to be inserted mgs.

This invention relates to mprovements in bo); fasteners and more particularly to a fastener which is particularly designed for use in connection with folders, cartons or other Japer containers and has for its primary object the provision of means whereby the container maybe quickly and securely closed. Another object of the invention is to provide a paper receptacle or container having one or more closure fiaps, said flaps being provided with interlocking means whereby their separation an the opening of the container is effectually prevented.

With the above and other objects in view, the invention. consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of a paper receptacle or container illustrating my improved fastener; Fig. 2 is a section taken on the line 2,2 of Fig. 1; Fig. 3 is a detail fragmentary perspective view of one corner of the container; Fig. 4 is a detail fragmentary plan view of one of the side fiaps; an Fig. 5 is a view of a slightly modified form of the invention illustrating a folder blank provided with my improve fas'tener.

The present invention is devlsed wit a view to providing secure fastening means for the closure fiaps of paper boXes or receptacles such. as that shown and described in my prior application filed June 11th, 1911, Serial Number 633,068, though it will be obvious that the invention is also applithrough the slits 13 in the body of the flap cable to folders, eommodity cartons and va- 5 and through the slits Min the looking rious other paper receptacles well known in tongues and the transverse slits 8 in the-ends the art. of the fiap' which coincide when the side folded and seoured together. The tongues 15 on the end flaps which extend through the looking tabs 9 and beneath the same prevent undue strain upon the shoulders 10 of the looking tabs by the pressure of the contents of the box or receptacle against the side walls thereof, and greatly strengthen the connection between the side flaps.

In carrying out the preferred embodiment flaps are of my invention, 1 provide the side walls of the box or receptacle with the closure flaps 5 and 6 respective The fiap 6 is provided ly. diate of its ends wi h the and at points interme spaced longitudmal slits or incisions 7 at points adjacent the ends of said flap the same is also provided with the ntersecting From the foregoing it will be readily l said tabs having slits therein to coincide seen that I have provided a fastener for with the transverse slits in said side Hap, paper receptacles which will securely retain said end flaps being provided with tongues the various flaps in their closed positions. upon their free edges for insertion through 5 e flaps may be very easily and qiiickly the coiiiciding slits iii said side fiap and the 5.

folded and secured by means of the looking looking tabs. tongues and tabs, the slits 7, 8 and 13 i'eadily 2. In a fastener of the Character dereceiving the same.

In Fig. 5 of the drawing I have illusti'ated my invention applied to an advei'tising folder, said fol ei' consisting of tlie recspaced longitudinal slits intermediate of its 60 ends, said fiap being' also provided in each eiid with intersecting longitudinal and tranlsverse slits, the other of said side fiaps having a plurality of looking tabs fornicd upon its free edge .for insei'tion through the G5 longitudinal slits of the first nained flap,

the looking tabs adiacent the eiids of said 15 of the folder. The flap 19 is then folded upon the short flaps. This latter flap is provided with a slit 7' to receive the locking tab 9' formed on the end of the flap 18 which is adanted to be folded upon the 20 flap 19. The flap 18 is also provided with spaced slits 13' to receive the tonguesl' wiich are cut out of the flapt 19. After the looking tab 9' has been inserted through the slits 7', the tongues 15 are then disposed through the slits 13' to coinplete the closure of the folder.

From the foregoing it is thought that the construction and operation o my invention will be fully understood. Paper receptacles which are st-ainped out in blanlr form may be provided with iny iinproved fastening means at an insignificant additional expense and While I have only illustrated in the drawing two forins of such receptaeles, it

Will be obvious that the invention may bo incorporated in any of the many different forms of the same which are now known in first named side Haps, said latter fiap being also provided with transverse slits at each end and adjacent to its attached edge, said end flaps having` tongues projecting from their free edges and ad'iacent to each of their ends, the respective tongues of said end first nained side flap.

8. In a fastener of wthe Character de- S0 scribed, a paper container having side and end fiaps, one of the side fiaps being provided With spaced longitudinal slits and also having transverse slits adjacent to the ends of said flap, the other of said side fiaps being the art with only shght and immaterial longitudinal slits of the first named flap, the end tabs of said latter flap being also provided with slits to eoincide with the transverse slits in said side flaps, said end flaps liaving tongues upon their edges for insertion through the coinciding slots in said side tlap and the locking tabs.

In testiinony whereof I hereuiito affix my signature in the presence of two witnesses.

40 from the spirit or principle of the invention. Having thus described the invention what is elaiined is z 1. In a fastener of the Character described, a paper container having side and 45 end flaps, one of the side flaps being provided at each of its ends with longitudinally and transversely eXtending intersecting slits, the other of the side flaps having looking tabs forined thereon to be disposed throuoh 50 t e longitudinal slits of the first named fiap,

Gopes of this patent may be obtained for five eents each, by addressng the Commissioner of l'atents, Washington, I).` 0.
